This is a set of optional RPM Steering Knuckles, with included Oversize 15mm Ball Bearings, and are intended for use with the Traxxas T-Maxx 1.5, 2.5 and E-Maxx monster trucks, as well as the Associated Monster GT. Stock bearings and axle carriers aren’t quite strong enough to handle the punishment monster truck owners dish out. In addition, more strength is needed at the axle carrier when offset wheels are used or when aluminum accessories and oversized wheels & tires add more weight and stress to the driveline. Once again, RPM steps in where no one else has! RPM has completely redesigned the axle carriers for the maximum amount of strength and durability and included some seriously beefy 15mm bearings to top it all off!

RPM axle carriers are sold in pairs. One truck will need two pairs to cover all four corners of a T/E-Maxx truck for complete, RPM bulletproof protection. RPM replacement oversized bearings are sold in sets of four bearings per package.
